Managing the Survey FrameSlide3

The Swiss Business Register (BR) contains

all enterprises and all establishments

that

generate an economic activity in Switzerland. The main information is updated permanently through different sources.

The BR is used by FSO as an address register for statistical surveys (survey frame, extrapolation basis). Other governmental agencies and cantons in Switzerland use BR for statistical or administrative purposes.

Maintenance strategy of the BR (1)

The maintenance strategy takes into account the following aspects:

Use of administrative sources (Social Security is the main one)

Use of feedbacks from surveys

Needs of the users

Enterprises are partitioned into various maintenance

groups by size and potential impact on public statisticsPlanning of the updates

Historical registerRules for dealing with conflicting informationSlide12

Maintenance strategy of the

BR

(2)

For maintenance

purposes, the enterprises are divided into three groups:Multi-establishments enterprises subject to Profiling:

Enterprises > 10 local units or > 100 employeesQuarterly collection (enterprise structure, employment and NACE per local unit)

Multi-establishments enterprises subject to Profiling Light:

Enterprises < 10 local units or < 100 employees

Maintenance strategy of the BR (3)

All enterprises with only one local unit:

ERST (quarterly survey on newly created enterprises)

 structure, reason of creation,

employment and NACE per local unit

QS-NACE  annual control survey of the economic activity covering all units over 5 yearsAdministrative sources (Social Security)  employment per enterpriseSlide14

BR: Basis of the

survey frame (1)

The

economical

statistical surveys are based on the

business register;The enterprise is the central statistical unit;At the moment, FSO uses only one survey frame for

all economical statistical surveys;

Each year

a new survey frame is provided

containing all

metadata

;

The

coordination of the drawing-samples

must

be insured. The burden

on enterprises

can

be reduced

by using this system

;

The

business register is continuously updated

during

the year

; the structural data

and all

statistical information

are

integrated (profiling, profiling light

, others

surveys);Slide16

BR: Basis of the

survey

frame

(2)

Each year the available statistical information (from administrative sources) is also integrated: employment and turnover;

The NACE code is updated on a regular basis;

All information has its own reference period (time stamp);

Survey Frame ≠ Structural Statistics (STATENT);

Survey Frame =

Structure

of the statistical units

at

the year A, enhanced with

statistical information

from year A or A-1 or A-2

according to

the update

schedule;

Structural Statistics

= Structure and statistical information corresponding to the same reference period of year A-2

A quarterly

report provides the observed changes during

Managing

the Survey

F

rame (2)

During the year when the survey frame is used, quarterly reports provide the main changes in the survey frame

(new entries, cessations or others changes).These changes can be used to describe the modifications in the population of the

survey and to help or support the extrapolation methods.

Checks in the population can also be performed in order to provide additional

information on structural

changes

.

Each year a new survey frame is prepared

as an

update

of the previous

frame

containing all the information

gathered throughout the

year.

All the rules of continuity are used. The purpose of this practice is to determine what information of the last frame may be transmitted to units of the new frame and under what circumstances

.Slide19

The changes are detected and treated following the rules that are explained in the «Manual of coordinated survey system for enterprises – SVS».Slide20
